Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed May 10, 1915. Serial No. 27,215.

To all whom it may concern:

Be it known that we, WILLIAM R. HAMIL- TON and FRANK "W. BERNEY, citizens of the United States, residing at Dewey, in the county of Washington and State of Oklahoma, have invented certain new and useful Improvements in Governor- Controlled Valve-Operating Mechanism, of which the following is a specification.

This invention relates to an improvement in governdr controlled valve operating mechanism, and the object is to provide means which is connected to a governor so that upon the operation of the governor the means will be actuated for operating the valves.

The invention consists of certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In th accompanying drawings Figure 1 is a perspective view, showing a portion of the motor casing broken away to more clearly set forth the method of controlling the supply of steam or gas to the rotor;

Fig. 2 is a view in elevation of the lever, valve and disk; and

Fig. 3 is a detail sectional view showing the manner of connecting the lever to the disk.

Fig. A is a detail sectional view showing the supply passages in the casing.

A, represents the casing of the motor, in which a rotor 1 is mounted. A shaft 2 is journaled in the casing and the rotor is mounted thereon. The casing A is provided with a steam inlet 3, from which channels A extend to the ports 5, a port being located in opposite sides of the casing. Needle valves 7 are slidably mounted in the casing and travel through and across the ports 5 for controlling the admission of steam or gas to the rotor.

Brackets 8 are connected to the casing A and the terminals of the valves 7 project through the brackets. Springs 9 surround the valves, one terminal is engaged by a nut 10 screwed upon each of the valves for normally forcing the valves outward to afford an unobstructed passage for the steam or gas through the ports 5. An adjustable collar 11 is mounted on the'needle valves 7 which is adapted to engage the brackets 8 for limiting the outward movement of the valves.

A governor consisting of a movable block 12 is mounted on the shaft 2, and an adjustable collar 13 is mounted on the shaft. Interposed between the collar 13 and block 12 is a spring 14 for exerting a pressure against the movable block 12 to prevent the block from moving toward the collar.

A generator B is provided with a shaft 15, w ich fits within the shaft 2. A stationary block 16 of the governor is mounted on the shaft 2, and a tapered hole is formed through the block 16, and shafts 2 and 15, in which a tapered pin 17 is received for looking the block and shafts together.

The blocks 16 and 12 of the governor are connected together by means of toggles 18. Mounted on the movable block 12 is a bifurcated or forked disk 19 which is fitted astride of the block. Lubricant cup 20 is connected to the disk, and formed in the disk and leading from the cup is an oil duct 21 for lubricating the surfaces of the block and disk to relieve any friction.

The disk is provided with two preferably round straight holes 22, one formed on each side of the disk. Levers 23 provided with round ends or knobs 24 are mounted on adjustable crutch heads 25. The crutch heads 25 are mounted on posts 26 connected to the casing A.

The rounded ends 24: are adapted to be received in the holes 22 of the disk and move longitudinally therein, upon the movement of the block 12.

When the rotor has been set in motion the speed of the rotor will be controlled by the governor, and as the movable block 12 is caused to move on the shaft against the tension of the spring 14:, the ends 24: of the levers will be caused to move lengthwise of the holes 22, thereby imparting motion to the levers 23 causing the free ends of the levers to be brou ht into engagement with the needle valves? for forcing them inward for cutting off the power supply to the rotor.

The timing of the actuation of valves 7 by the levers 23 is controlled by the adjustment of the heads 25, and with a connection such as is provided for the levers with the disk 19 carried by the block 12 there is a positive actuation or movement of the levers without any lost motion, as the rounded ends 24 fit the holes 22 sufficiently snug to prevent any lateral movement, yet the ends 24 are capable of movement within the holes without affecting the operation of the block 12. A hinge connection is formed between the levers and disk with no play or friction, and at the same time extends the motion of the governor block 12 to the needle valve by the outer end of the lever coming in contact with the ends of the valves 7. The levers afiord a support for the disk and maintain it off from the bottom of the groove in block 12.

We claim 1. The combination of a governor having a stationary and movable member, an annular groove arranged within said movable member, a shifting block received within said annular groove, levers having their ends received in orifices on opposite sides of said shifting block aflording a sliding engagement between the levers and movable members whereby the levers will be actuated upon the movement of the movable member, and rotatably adjustable supports for said levers whereby said shifting block and levers are capable of vertical adjustment.

2. The combination of a governor having a stationary and movable member, an annular groove arranged within said movable member, a shifting block having an open slot therein whereby the shifting-block is and movable member, whereby the levers will be actuated upon the movement of the movable member, and rotatable adjustable supports for said levers whereby said shifting block and levers are capable of vertical adjustment.

8. The combination of a motor having a governor on the shaft thereof consisting of a stationary and movable member, a shifting block capable of vertical movement associated with the movable member, a lever having a sliding connection with said shifting block and a plurality of actuated mechanisms arranged laterally of said shaft, rotatably and horizontally-adjustable supports for said levers whereby said levers and actuated mechanisms may be alined.

In testimony whereof We aflix our signatures in the presence of two witnesses.
